In C++ specifies constructors and conversion operators that don't allow implicit conversions or copy-initialization. In C# declares a user-defined type conversion operator that must be invoked with a cast. For MS SQL Server for-xml-EXPLICIT mode use the [for-xml-explicit] tag

Does implementing Interface both implicit and explicit make sense?
I'm currently studying for my MS 70-515 exam. In one of the practices the author implements an interface both implicit as well as explicit. The explicit implementation just calls the implicit implementation. The explicit implementation is just…

I played around with explicit constructors and their behavior, so I created this class:
#include

{
public:
explicit X(void)
{
std::cout << "Default constructor\n";
}
explicit X(X const& x)

ASP.NET: explicit vs implicit localization?

When to use explicit specifier for multi-argument constructors?
I have recently learned about the explicit specifier.
Suppose we have:
f( W, W, W );
Now if we do
f( 42, 3.14, "seven" );
The compiler will attempt the following implicit conversions:
f( W(42), W(3.14), W("seven") );
If we have defined matching…

Why does position of explicit template instantiation matter
Say I declare a template class A in a.h
#include
template
class A {
public:
void print(std::ostream& out);
};
And define the print method in a.cpp (with explicit instatiation for true and false)
#include "a.h"
